specific Embodiment approach 1

[0034] Specific implementation mode 1: refer to Figure 1 to Figure 8 Specifically illustrate this embodiment, a kind of scheduling method based on GPS technology described in this embodiment to prevent buses from concentrating on stations, and described scheduling method includes:

[0035] Step 1. Store the length L of the bus line, the tolerance ρ to the ideal spacing deviation, the direction of the bus line, the coordinates of the starting and ending points of the bus line, and the coordinates of the line passing through the intersection in the system.

[0036] Step 2, start searching from the first bus closest to the starting point of the line, make i=1, obtain the number N of buses running on the same time line according to GPS, each bus coordinate (x i ,y i ), i∈(1,N), the running speed v of each bus i , combine the data in step 1 to calculate the running distance J between car i and car i+1 i,i+1 , and calculate the ideal spacing S of the lines L ,

[0037] Step 3:...

specific Embodiment approach 2

[0057] Specific embodiment two: This embodiment is to further explain the dispatching method based on GPS technology described in specific embodiment one to prevent buses from concentrating on stations. The first bus starts to retrieve, let i=1, obtain the number N of buses running on the same time line according to GPS, and the coordinates of each bus (x i ,y i ), i∈(1,N), the running speed v of each bus i , combine the data in step 1 to calculate the running distance J between car i and car i+1 i,i+1 , and calculate the ideal spacing S of the lines L The process is:

[0058] The GPS coordinates of each intersection on the bus operation line, the total number of intersections is N j , the data whose coordinates are (a,b) and the ratio of the distance in GPS to the actual distance on the road is 1:γ, γ is a natural number, which is stored in the system as basic data, and the real-time coordinates (x,y) of each bus are obtained by GPS ), the number of intersections m betwe...

specific Embodiment approach 3

[0065] Specific embodiment three: this embodiment is to further illustrate a kind of GPS technology-based dispatching method that prevents buses from concentrating on stations as described in specific embodiment one or two. In this embodiment, in step 3, use i car and Running distance J between i+1 cars i,i+1 , the running distance J between i+1 car and i+2 car i+1,i+2 and the speed v of car i i , i+1 car speed v i+1 and the speed v of the i+2 car i+2 Calculate the expected distance S between car i and car i+1 i,i+1 and the expected distance S between car i+1 and car i+2 i+1,i+2 The method is:

[0066] When i = 1, that is, when the retrieval is performed for the first time, the expected spacing is:

[0067] S 1,2 =J 1,2 +(v 2 -v 1 )×180,

[0068] S 2,3 =J 2,3 +(v 3 -v 2 )×180,

[0069] Among them, the unit of 180 is seconds, and 180 seconds represents a scheduling period of 3 minutes.

[0070] When i≠1, that is, when the cycle has started, the expected distanc...

Abstract

The invention provides a scheduling method preventing centralized arrival of buses on the basis of a GPS technology, and relates to the field of urban road traffic control. The method aims to solve the problems that in the prior art, arrival punctuality of the buses is poor and arrival time of the buses is not balanced. According to the method, retrieval is performed on the first bus nearest to a route starting point, i is equal to 1, the number, coordinates and running speeds of buses running on a route at the same time are obtained according to a GPS, a ratio interval is judged by calculating running distance, ideal distance and predicted distance between two buses and the ratio of the predicted distance of the two buses to the ideal distance between the two buses, i is equal to i plus 2, i is smaller than N, all the buses are scheduled repeatedly, the average speed of all the buses is calculated, whether operation of the buses is finished or not is judged, data of the running buses are obtained again if operation is not finished, and scheduling is achieved. The method can be used for vehicle scheduling.

Description

technical field [0001] The invention relates to a scheduling method based on GPS technology to prevent buses from concentrating on stations. The utility model belongs to the field of urban road traffic control. Background technique [0002] Conventional public transportation has the characteristics of large capacity, convenience, low price, and low pollution. Vigorously developing public transportation has become a priority solution to alleviate road congestion and solve the problem of urban residents' travel difficulties. However, due to various adverse road traffic conditions, sudden passenger flow and other factors, there may be deviations between the actual arrival time of the bus and the setting of the timetable, and multiple buses may arrive at the same time, resulting in the phenomenon of centralized bus arrival. . When the phenomenon of concentrated bus arrival at the station occurs, it means that the waiting time of subsequent passengers will be affected, which wi...
